Description
The 279 x 80 x 30 Old Style Stator Knife is a precision-ground stationary cutting component for earlier configurations of Virtus Equipment and ZERMA America ZSS, ZIS, ZWS, ZRS, and ZBS series shredders. The stator knife provides the fixed cutting edge that works in opposition with the rotating E-type square rotor knives to shear and reduce plastic material to the target output size. This old style knife is designed for the earlier machine configurations in the ZSS/ZIS/ZWS/ZRS/ZBS series — it is essential to verify your machine’s build date and configuration before ordering to ensure correct fitment.

Key Features
Old Style Configuration: Designed specifically for earlier ZSS/ZIS/ZWS/ZRS/ZBS machine configurations — verify your machine’s build date and style before ordering to ensure correct fitment.
Precision-Ground Cutting Edge: Ground to exact dimensional tolerances for proper cutting gap alignment with E-type square rotor knives — essential for consistent output size and minimal fines generation.
Robust 80 × 30 mm Profile: Heavy cross-section delivers the structural rigidity required for the high-torque cutting forces of ZSS/ZIS/ZWS/ZRS/ZBS series shredder operation.
D2 Tool Steel Construction: Manufactured from premium 1.2379 high-carbon tool steel heat-treated to 58–62 HRC for outstanding wear resistance, edge retention, and extended service intervals.
50+ Years of Manufacturing Expertise: Produced by a manufacturer with over 50 years of combined steel production and knife manufacturing experience for unmatched consistency and quality.
Direct OEM Replacement: Precision-machined to original equipment specifications for guaranteed fitment and performance on compatible old style machine configurations.
The 80 × 30 mm cross-section delivers the structural rigidity required for the high-torque, low-speed cutting action of the ZSS/ZIS/ZWS/ZRS/ZBS shredder series. These machines operate at lower rotor speeds than conventional granulators, generating high cutting forces that demand robust knife construction and reliable material quality to maintain consistent performance over extended service intervals.
All Virtus Equipment Direct knives are manufactured from premium D2 tool steel (DIN 1.2379) with specialized heat treatment to 58–62 HRC, delivering outstanding wear and abrasion resistance in continuous industrial operation. Our knives are produced by a manufacturer with over 50 years of combined steel production and knife manufacturing experience, ensuring consistent metallurgical quality and reliable performance across every knife we supply.
